FAN SUCTION VENTILATOR.

Application filed. August 18, 1924. Serial No. 732,860.

,To all whom it mag concern:

Be it known that I, DANIEL' BECK, a cit-izen of the United States, residing at Okmulgee, in the county of Okmulgee and State of Oklahoma, have invented a new and useful Fan Suction Ventilator, of which the follow ing is a specification.

This invention aims to provide a simple means whereby the wind may be made e:t'- liective to draw the heated air out of an attic or other part of a building.

It is within the province ofthe disclosure to improve generally and to enhance the utility of devices of that sort to which the invention appertains.

Although a preferred embodiment of the invention has been shown, it will be undcrstood that a. mechanic, working within the scope of what is claimed, may make such changes as his skill may suggest, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 is a side elevation showing a device constructed in accordance with the invention; Figure 2 is a vertical longitudinal section wherein parts appear in elevation; and Figures 3 and 1. are sections taken, respectively, on the lines 38 and 4+4 of Figure 2. Figure 5 is a section on the line 55 of Figure p The numeral 1 designates a flue, adapted to communicate with a garretor other part of a building to be ventilated. The flue. 1 carries internal transverse rods2, or other suitable devices, supportinga bearing 3 having an upstanding pointed spindle 4.

The numeral 5 designates a cowl, including a collar 6 located about the upper end of the: fine 1. The collar 6 is connected to a sleeve 7. Transverse rods 8 or the like, carried by the collar 6 and the sleeve 7 support a tubular bearing 9 within which the spindle 4 extends, the spindle cooperating with the bearing 9 to support the cowl 5 for rotation about a vertical axis. The cowl 5 comprises a tubular head 10, the axis of which is horizontal and approximately at right angles to the axis of the flue 1. The head 10 includes vertically offset parts 11 and 12, of tubular form, the part 12 being connected at 14 to the upper end of the sleeve 7, as shown in Figure 1.. The partsll and 12 of the head 10 are connected by a drum 15, the axis of which is disposed at an angle of about forty- .five degrees to the axis of the head '10 and to the axis of the flue 1.

.of the drawings. 'member 16 may head into the wind, a vane 25 is mounted on the part 11 of the tubular The wider end of a funnel-shaped inlet I member 16 is ioined'to the outer end of the part 12 of the head 10, the inner end of the inlet member 16 extending withinthe drum 15, as shown in Figure 2, and terminating in a rim 17, the axis of which coincides with the axis of the drum 15. Noting the point at which the reference character 18 is applied in Figure 2, it will be observed that,

measured longitudinally of the head 10, the

sleeve 7 of the cowl is of about the same -di-.

' upwardly, so that, as shown in F igure, 3, there is a space about the inlet member 16,

which permits the air to move upwardly and be acted upon by the wind wheel 27, hereinafter described.

The inlet member 16 and the rim 17 thereof carries rods 20 or the like, supporting a bearing 21. A lubricantis supplied to the bearing 21 through a conduit 22 having a valve 23, the conduit communicating with an oil reservoir 24 mounted on the cowl 5 and extended between the members 12 and 11 of the cowl, as shown clearly in Figure 2 In order that the inlet head 10 and is sustained by braces 26.

The numeral'27 marks a wind wheel including a shaft 28 journaled in the bearing 21, the hub 29 and blades projecting from the hub, each blade including a shank 30 anda laterally extended and inwardly inclincd arm 31. The shanks 30 of the blades are so positioned, as shown in Figures 3 and 1, that they will be acted upon by the air passing through the inlet member 16,

whereas the arms 31, being located about the rim 17 of the inlet member, will tend to draw the air upwardly through the line 1, the sleeve 7- and the drum 15, and force the air outwardly through the partll of the head 10all of. which will be understood readily when Figure 2 of the drawings is noted.

In practical operation, the vane 25 keeps the inlet member 16 in such a position that it will receive the wind, the cowl 5 rotating with respect to theflue 1, the cowl being supported by the bearing 9 on the spindle 4 of the flue 1. The hot air within the gar ret or other apartment which is to be ventilated, moves upwardly through the parts 1, 7 and 15 and is forced outwardly through the part 11 of the head 10, by the arms 31 of the wind wheel 27. The wind, entering the inlet member 16, and passing through the rim 17, cooperates with the shanks 30 of the wind wheel to impart rotation to the wind wheel, so that the wind wheel will serve as a ventilating machine, as aforesaid. The operator may open the valve 23 at any time, to permit a lubrication of the bearing 21, or the valve 23 may be so set as to afford the necessary continuous supply of lubricant to the bearing 21.

Having thus described the invention, what is claimed is 1. In a device of theclass described, a flue, a cowl comprising a head located about at right angles to the axis of the flue, the head including axially offset parts and a drum joining said parts, the axis of the drum being located at an acute angle to the axis of the head and to the axis oi the flue, and a sleeve connected to one of said parts otthe head and cooperating with the flue; means for supporting the cowl for rotation with respect to the flue; a conical inlet member in one end of the head; and a wind wheel supported for rotation in the drum, the wheel comprising blades including shanks extended across the inner end of the inlet member, and circumferentially inclined arms located outwardly of the inner end of the inlet member, whereby air entering the inlet member will actuate the wind wheel to produce suction in the flue.

2. In a device of the class described, a

flue, a cowl comprising a head located about at right angles to the axis of the flue, the head including axially oilset parts and a drum joining said parts, the axis of the drum being located at an acute angle to the axis of the head and to the axis of the flue, and a sleeve carried by one of said parts of the head and cooperating with the flue; means for supporting the cowl for rotation with respect to the flue; a conical inlet memher in one end of the head; and a wind wheel supported for rotation in the drum, the wheel comprising blades extended across the inner end of the inlet member, and prolonged beyond the inner end of the inlet member to draw air through the flue and to force air out of the head.

3. In a device of the class described, a flue; a cowl comprising a head located about at right angles to the axis of the flue; and a sleeve cooperating with the flue; means for supporting the cowl for rotation with respect to the flue; an inlet member in one end of the head; a wind wheel located at the inner end of the inlet member and disposed at an acute angle to the axis of the head and to the axis of the flue, the wind wheel extending across the inner end of the flue and outwardly beyond the flue; and means located within the inlet member for supporting the wind wheel for rotation, thereby leaving the space about the inlet member, and a space in front of the inlet member, unincumbered.

In testimony that I claim the foregoing as my own, I have hereto atlixed my signature.

DANIEL BECK.
